The Null Device

Men are from Pluto, women are from Mercury

A biologist and a sociologist have put forward a new theory of brain development and mental disorders. Crespi and Badcock's theory posits a spectrum running between autism and related social dysfunctions on one side and schizophrenia, depression and bipolar disorder on the other, with the struggle between maternal and paternal genes in the womb determining where the child's neurology will fall on this axis:
Dr. Crespi and Dr. Badcock propose that an evolutionary tug of war between genes from the father’s sperm and the mother’s egg can, in effect, tip brain development in one of two ways. A strong bias toward the father pushes a developing brain along the autistic spectrum, toward a fascination with objects, patterns, mechanical systems, at the expense of social development. A bias toward the mother moves the growing brain along what the researchers call the psychotic spectrum, toward hypersensitivity to mood, their own and others’. This, according to the theory, increases a child’s risk of developing schizophrenia later on, as well as mood problems like bipolar disorder and depression.
It was Dr. Badcock who noticed that some problems associated with autism, like a failure to meet another’s gaze, are direct contrasts to those found in people with schizophrenia, who often believe they are being watched. Where children with autism appear blind to others’ thinking and intentions, people with schizophrenia see intention and meaning everywhere, in their delusions. The idea expands on the “extreme male brain” theory of autism proposed by Dr. Simon Baron-Cohen of Cambridge.
“Think of the grandiosity in schizophrenia, how some people think that they are Jesus, or Napoleon, or omnipotent,” Dr. Crespi said, “and then contrast this with the underdeveloped sense of self in autism. Autistic kids often talk about themselves in the third person.”
